Patented Mar. 14, 1939 PATENT OFFIQE LUBRICATING SYSTEM FOR FUR SEWING MACHINES Caesar Bonis, Brooklyn, N. Y. 7 Application April 30, 1938, Serial No. 205,237

2 Claims. (01. ls is).

This invention relates to lubricating devices generally and more particularly for such devices which are specially adapted for use in connection with fur sewing machines, and has for one of its objects the provision of a lubricating device of this character which will be actuated to function by the vibrations set up during the operation of the machine.

Another object of the invention is the provim sion of such a lubricating device contained in the cover of a fur sewing machine and which comprises a reservoir in the said cover, said reservoir being-sealed by a gasket and a plate'containing tubes in which there are wicks that ex- 15 tend into the reservoir to become saturated with the lubricant, the said lubricant falling or dropping upon the moving parts of the machine due to the vibration set up by the said parts when in operation.

20 Another object is to produce a device of the character described in which the maximum simplicity of construction and operation is secured.

Other objects and advantages will appear as the nature of the improvements is better understood, the invention consisting substantially in the novel arrangement and co-relation of parts herein fully described and illustrated in the accompanying drawing, wherein similar reference characters are used to describe corresponding 30 parts throughout the several views, and then finally pointed out and specifically defined and indicated in the appended claims.

The disclosure made the basis of exemplifying the present inventive concept suggests a practi- 35 cal embodiment thereof, but the invention is not to be restricted to the exact details of this disclosure, and the latter, therefore, is to beunderstood from an illustrative, rather than a restrictive standpoint.

40 The inventive idea involved is capable of receiving a variety of mechanical expressions, one of which, for the purpose of illustration, is shown in the accompanyinf drawing, in which- Figure 1 is a fragmental front view partly in 45 section of a fur sewing machine embodying my invention;

Fig. 2 is a sectional view taken on line 2-2, Fig. 1; v

Fig. 3 is a top plan view thereof; and

50 Fig. 4 is a bottom plan view of the cover looking :from the bottom of Fig. 2.

Referring now to the drawing in detail, 5 indicates the frame of a fur sewing machine in which is housed the operating mechanism there- 55 of, a portion 6 of such mechanism being shown in dot and dash lines Fig. 1. Suitably maintained over the said frame 5 is a cover 1 which is provided at the top thereof with a reservoir 8 for containing a suitable lubricant as for instance lubricating oil.

The cover 'I is provided with an opening 9 at the top thereof so as to bring the interior of the reservoir into direct communication with the atmosphere. An oil cup In which may be opened and closed by means of a cap 1a is provided at 10 the top of the coverthrough which lubricating oil may be admitted into the interior of the reservoir. At the bottom of the reservoir which may be of any suitable depth there is provided a plate H which is secured to an inner flange I4 defining the reservoir by means of screws I2. A rubber gasket i3 is interposed between the flange l4 and the plate H to make same liquid tight.

The plate Il may be provided with a plurality of perforations in which are secured short tubu- 2 lar sections IS in which are suitably held as by knots l6 wicks I! which extend into the interior of the reservoir and which extend outwardly of the tubes as at l8. If desirable I may provide one or more bent tubes I9 to lead lubricating oil to a point in the machine not within the area directly below the reservoir.

In order to prevent the oil in the reservoir from flowing through the cover, when the said cover is taken ofi the machine and placed in inverted position, I provide a valve which'comprises a ball 20 which is housed in a conical shaped basket 2| which is secured to the cover by means of a screw 22. It will be seen that when the cover is in inverted position the ball will overlie and close the opening 9 and prevent the oil from flowing out of the reservoir.

It is to be understood that in practice the wicks l1 prevent the free flow of oil from the reservoir to the interior of the machine and absorb 40 only a sufficient amount so that the oil will only drop down and lubricate the mechanism 6 at intervals during the actual running or operation of the machine.

From the foregoing it will be seen that I have provided a simple yet efficient lubricating device for fur sewing machines which will automatically lubricate the working parts of the machine during the actual operation thereof, said lubricating action being caused by the vibrations set up 5 in the machine by the running or operation thereof.

It will further be seen that with the installation of my improved lubricating device the conthe said opening to close the same when thecover is in inverted position, lubricant admitting means in communication with the reservoir, closure means for the said reservoir, and wicks extending from the through the closure and outwardly thereof to permit of periodical lubricating action through the said wicks when the machine is in operation.

2 A lubricating device adapted for use in coninterior of the reservoirs nection with sewing machines having a frame containing the operating mechanism therein, a cover for the said machine, a lubricant reservoir in the said cover, lubricant admitting means in communication with the reservoir, said cover having an opening therein in communication with the reservoir, a normally open ball valve in the reservoir below the said opening to close same when the cover is in inverted position, a perforated plate secured to the cover at the mouth of the reservoir, a sealing gasket interposed between the plate and cover, tubes in the plate perforations, wicks extending outwardly from the interior of the reservoir through the said tubes to permit of periodical lubricating action through the said wicks when the machine is in operation, and means for preventing the wicks from dropping through the tube.
